PLAN AND SCOPE OF THE INSTITUTE 

THE Institute of Industrial Research was 
founded by Allerton S. Cushman, Henry A. Gardner 
and N. Monroe Hopkins, December i, 1910, as a 
company duly incorporated under the laws of the District 
of Columbia. The articles of incorporation declare that 
the objects of the corporation shall be: 

"i. To investigate and improve processes of manufac- 
ture and to cooperate with manufacturers in the reduction 
of costs and the utilization of by-products and waste. 

"2. To investigate and improve general metallurgical, 
mining and agricultural operations, so as to improve their 
efficiency and to disseminate information in regard to such 
improvements. 

"3. To study the problems of paint technology, electri- 
cal engineering, and electrochemistry; and to institute 
economies and improvements in the manufacture of fer- 
tilizers and general chemicals. 

"4. To train and instruct graduates of scientific and 
technical schools and other qualified persons in industrial 
research, and to aid them in obtaining work for which 
they are particularly fitted; and in general to do and per- 
form every lawful act and thing necessary or expedient to 
be done or performed for the efficient and profitable con- 
ducting of said business, as authorized by the Laws of 
Congress, and to have and exercise all powers conferred 
by the laws of the District of Columbia upon said corpora- 
tion." 

The articles of incorporation were purposely drawn so 
as to provide for the expansion and development of the 
Institute's work on the broadest possible lines. The 
branches of the work which have been given the most 
attention include metallurgical problems, with especial ref- 
erence to the protection and conservation of the industrial 
metals; agricultural chemistry, land and fertilizer prob- 
lems; paint technology in all its branches; food and drug 
problems with especial reference to the interpretation and 
compliance with Federal and State legislation; chemical 



industry, Including the Improvement and extension of pres- 
ent processes and the development of new ones; road 
building and paving problems with especial reference to 
specifications, inspections, advice and Investigations In co- 
operation with municipalities and other corporations or 
Individuals who desire to retain expert assistance, with 
chemical and mechanical testing and examination. Elec- 
trochemistry and electrical and chemical engineering In 
general Is also made a strong specialty. Patents and their 
development have proved to offer a field in which the serv- 
ices of the Institute have been useful. Although the Insti- 
tute does not undertake to do the work of patent solicitors 
or attorneys. Its location In the City of Washington and Its 
broad equipment for Investigation enables patent attorneys 
and Inventors to avail themselves of special facilities for 
working out their problems. 

The organization of the Institute is built up on the same 
plan as some of the scientific bureaus of the Federal Gov- 
ernment, in which most of the Divisional Chiefs received 
their training through many years of official service. The 
Institute, however, is quite independent of the Govern- 
ment, and is supported entirely by fees and retainers 
received from clients for service rendered. Ordinary 
commercial analytical work and testing Is carried on to a 
limited extent, although it is not a principal object of the 
Institute unless the results sought have a direct bearing on 
important development problems. 

Although research must be essentially scientific and car- 
ried on along scientific lines, the intention Is to interpret all 
results obtained In a practical way, so that they will be 
useful to manufacturers and others who avail themselves 
of the advantages that the work of the Institute offers. 

Many of the great industrial associations of the United 
States have been within the last few years carrying on 
research work as a business asset. It Is naturally more 
economical for such associations to avail themselves of an 
organization and equipment already complete than to es- 
tablish and endow their own laboratories. Already seve- 
ral of the most important representative organizations 



have completed arrangements with the Institute to carry 
on research work in their respective lines, and the results 
obtained have fully justified this cooperation. 

The laboratories and offices of the Institute are admira- 
bly housed in a new and specially designed building which 
is located on a beautiful site facing on Potomac Park at 
19th and B Streets Northwest. It is very near the Bureau 
of American Republics and about five minutes walk from 
the White House. 

The building contains a large lecture hall, which also 
serves the purpose of a library and demonstration room. 
It is equipped with lantern Baloptlcon and projector. This 
room is available without charge as a meeting place for 
technical committees of various learned societies meeting 
in Washington. 

The description of the various laboratories and their 
equipment will be found under the chapter describing the 
separate divisions of the work.

DIVISION OF METALLURGY 

ALLERTON S. CUSHMAN, A.M., Ph.D., in Charge of Division 

THE Division of Metallurgy Is prepared to under- 
take work in all problems in the line of metallurgy, 
including the mining, chemistry and evaluation of 
fuels and industrial minerals. Special attention and study 
have been given to corrosion problems and methods of 
overcoming these difficulties. Although not strictly speak- 
ing a metallurgical problem, examinations and reports on 
water supplies are handled in this Division. This work is 
taken up in both the sanitary and industrial phases of the 
subject, and includes sewage and drainage problems. In 
many cases the rapid corrosion of boilers and metallic con- 
tainers is principally due to the character of the water sup- 
ply, which may easily be modified by proper treatment. 
Refrigeration engineering and boiler practice introduce a 
number of problems which only the trained chemical engi- 
neer, with a full laboratory equipment at his service, can 
hope to solve. The conservation of metals and minerals 
of all kinds, the utilization of by-products and saving of 
wastes are among the subjects of great importance, on 
which the advice and work of this Division is frequently 
called for. 

The Division of Metallurgy is under the direction of 
Dr. Allerton S. Cushman, assisted by the general staff of 
the Institute. Dr. Cushman took his Bachelor's degree in 
chemistry at the Worcester Polytechnic Institute, under 
Professor Leonard Kinnicutt, in 1888. He then went to 
Germany and studied metallurgy under Professors Richter 
and Ledebur, at the Royal School of Mines in Freiberg, 
Saxony. He also studied for a time in the laboratory 
under the celebrated Professor Bunsen, at Heidelberg Uni- 
versity, Bavaria. After some years' professional practice 
and teaching in the West, he went to Harvard University, 
where he took his Master's and Doctor's degrees, under 
Professors Jackson, Hill and Theodore Richards. For 
three years Dr. Cushman worked under Dr. H. W. Wiley 
in the United States Bureau of Chemistry, and was then 



made Assistant Director of the United States Office of 
Public Roads in Charge of Chemical and Physical Investi- 
gations, which position he held for six years until Novem- 
ber, 1910.

DIVISION OF PAINT TECHNOLOGY 

HENRY A. GARDNER, in Charge of Division 

THE Division of Paint Technology is under the 
direction of Mr. Henry A. Gardner, Assistant Direc- 
tor of the Institute, who is well known as a writer and 
authority on paint problems. Mr. Gardner has acted as 
Director of the Scientific Section of the Paint Manufac- 
turers' Association of the U. S., and has been for many 
years in charge of the experimental work that has been 
carried on by this Association. This work, which now 
forms one of the chief activities of this Division, is being 



"TTT 




Corner of Paint Testing Laboratory 

continued under Mr. Gardner's supervision in the specially 
designed and thoroughly equipped paint laboratories of 
the Institute, where every facility is afforded for its prose- 
cution in a thoroughly practical as well as scientific manner. 
The extensive exposure tests in different sections of this 
country, which were designed to determine the comparative 
merits of protective coatings and paint products for various 
structural materials, are being continued and inspected 

11 



from time to time in order that reports and bulletins may 
be issued and information distributed. Additional system- 
atic exposure tests have recently been undertaken by this 
Division on the Institute grounds at Washington, in con- 
junction with important laboratory researches to determine 
the physical and chemical properties of oils and oil mix- 
tures. 




Paint Tests on Grounds of The Institute of Industrial Research 

These tests are made upon Panels of Wood, Steel, and Cement. Several hundred 
different kinds of Paints and Paint Products are being tested in this practical fashion. 

This Division does not undertake the examination or 
commercial analysis of proprietary brands of paint or var- 
nishes, with the object of furnishing reports or certificates 
regarding their comparative value or relative durability. 
The Division Is, however, in a position to carry on research 
work to determine the usefulness of various products as 
paint constituents. Various materials which appear not to 
be suited for certain specific uses, and regarding which 

12 



1 



there is little information on record, are often found upon 
Investigation to be subject to treatment that renders them 
satisfactory, or they may be found to possess characteristics 
which make them of great value in certain lines of manu- 
facture. Study of such products, with a view to working 
out methods for their utilization, will be undertaken. 

Advice to engineers, architects or painters regarding the 
better types of protective coatings for the exterior or in- 
terior of buildings is given out from time to time without 
charge. In bulletin form. The regular serial bulletins of 
the Scientific Section of the Paint Manufacturers' Associa- 
tion are still being carried on. 

Consultation upon special problems which demand in- 
vestigation work will be undertaken for clients at charges 
commensurate with the service. The study of oils, oil 
substitutes, thinners, primers, driers, and waterproofing 
compounds represents an important branch of the work of 
this Division, In which its services are available. This 
Division cooperates with the other Divisions In working 
out the best treatment for protecting various materials of 
construction, among which may be instanced protective 
coatings for the Industrial metals, particularly iron and 
steel, and cement mortar and concrete structures.

View of One of the Chemical Laboratories 



DIVISION OF FOODS, DRUGS, AND 
AGRICULTURAL CHEMISTRY 

CHARLES A. CRAMPTON, M. D., Ph.C, in Charge of Division 

THIS Division handles all problems relating to the 
manufacture and marketing of food and drug prod- 
ucts. Within the past few years much legislation has 
been enacted regulating the production and sale of mate- 
rials and preparations intended for use as food or medicine. 
The Food and Drugs Act and the Meat Inspection Act 
under the control of the United States Department of 
Agriculture, the Oleomargarine Law, the tariff acts relating 
to tea, and the inspection of antitoxine manufactories 
under the Treasury Department, may be cited as instances 
of Federal laws of this character, and most of the States 
have enacted laws governing either dairy products or food 
products in general. Proposed legislation is now before 
committees of Congress which, if enacted into law, would 
very greatly extend existent governmental control over 
commerce in food products. 

This Division of the Institute is admirably equipped for 
dealing with all matters arising under present or proposed 
laws controlling or regulating the manufacture and sale 
or the importation for sale of food and drug products. It 
will undertake cases for clients before the Board of Food 
and Drug Inspection, the various Departments of the Gov- 
ernment charged with the execution of such laws, and the 
Federal Courts. It will represent individual clients or 
groups of manufacturers before Committees of Congress, 
concerning impending legislation, and it will give advice 
to manufacturers and dealers in regard to meeting the re- 
quirements of food control by changes and improvements 
in methods of manufacture, handling, labeling and mar- 
keting. In addition to matters arising under the various 
laws, the Institute solicits correspondence in regard to all 
possible investigations connected with the food and drug 
industries in the direction of improvements, economies, 
utilization of waste materials, development of new prod- 
ucts, etc. Problems common to entire lines of industries 
are particularly desired. 

15 



This Division has specialized quite extensively in the 
analysis of soft drinks and soda-water beverages, and, as a 
result, has become equipped with all the apparatus neces- 
sary for analytical and research problems in this field. 
The staff of this Division have specialized to a consider- 
able extent in research work on tea, coffee, and coloring 
matters used in food products. Researches are now being 
conducted in order to improve the processes of analyzing 
teas and coffees and for identifying the coloring matters 
occurring in food products. 

Another line of activity in this Division is that of work- 
ing out methods for analyzing different products of a 
manufacturing house. It often happens that a concern 
confronted with a peculiar or complex mixture is unable 
to arrive at a satisfactory method of analysis, and this 
laboratory takes up the problem and furnishes them a reli- 
able method for arriving at the data desired. Advice is 
also given regarding formulas and the improvement of 
existing prescriptions, especially with reference to their 
permanency and attractiveness as commercial articles. 
Toxicological and bacteriological work is also carried out 
in this Division. A subdivision is now being established to 
carry on work in fermentology. 

The efficiency of the Division in dealing with matters of 
Government control of food and drug products is greatly 
enhanced by the long experience of the men in charge of 
this work, in the branches of the Government which deal 
with the laws pertaining to such regulation. 

The Chief of the Division, Dr. Charles A. Crampton, 
served twenty years as Chief Chemist of the Internal Reve- 
nue Bureau of the Treasury Department, and prior to that 
time several years as Dr. Wiley's principal assistant in the 
Bureau of Chemistry of the Department of Agriculture. 
While in the Department of Agriculture he participated 
in the investigations (see Bulletin No. 13) which furnished 
the foundations for the present Pure Food and Drug Act, 
and in the Treasury Department he had charge of the 
technical administration of the laws taxing various food 
and drug products, such as oleomargarine, renovated and 

16 



adulterated butter, fermented and distilled liquors, sugar, 
etc. He is also thoroughly familiar with customs matters, 
having served on numerous commissions for fixing draw- 
hack rates, etc., which equips him for expert work before 
Customs Courts and the Tariff Commission. He is espe- 
cially expert in his knowledge of the operation of the de- 
natured alcohol law, having had charge of its administra- 
tion since its inception, and having made three trips to 
Europe for the Government in connection with its enforce- 
ment. In addition to his knowledge of the various laws. 
Dr. Crampton is thoroughly qualified to take charge of all 
possible investigations connected with the food and drug 
industries, and his services are available for general work 
involving organic analysis of the highest character. 

The Assistant Chief of the Division, Mr. H. C. Fuller, 
was employed in the Bureau of Chemistry about five years 
before becoming connected with the Institute, during which 
time he testified as an expert witness for the Government 
in many cases of prosecution under the Food and Drugs 
Act. Prior to his connection with the Bureau of Chemis- 
try he was in the employ successively of large drug manu- 
facturing concerns, such as the M'allinckrodt Chemical 
Works and Parke, Davis & Company, for a period of four 
years. He has, therefore, had experience both in practical 
commercial work and in Government control work, giving 
him a breadth of training which has fitted him most thor- 
oughly for the work of the Institute.

DIVISION OF MILL PROBLEMS 

GEORGE W. GOGGESHALL, Ph.D., in Charge of Division 

INDUSTRIAL RESEARCH demands the fullest cooperation 
between the producer or manufacturer and the investi- 
gation laboratory. It frequently becomes necessary to 
adapt laboratory results to the mill scale of operation, and 
in addition to this many problems are best studied in the 
actual field of manufacturing operation. The Division of 
Mill Problems has been organized to deal particularly with 
this phase of the work. The Division is under the super- 
vision of Dr. George W. Coggeshall, who is especially 
fitted by education and training to direct this work. Dr. 
Coggeshall received his bachelor's degree at Grinnell, in 
1890; he then went to Germany and took his doctorate 
under the celebrated Professor Ostwald, at Leipzig. He 
was for several years instructor in Physical Chemistry at 
Harvard University, and for the last ten years has been 
engaged in manufacturing and applied chemistry. A spe- 
cialty is made of designs and estimates for modernizing 
old industrial plants and the construction of new ones. 
The adaptation of patented processes and products to the 
commercial scale of operation is a branch of the work 
which it is believed will be found useful by inventors and 
capitalists who are attempting to develop new lines of in- 
dustry or improve old ones. Dr. Coggeshall's special 
training, taken in conjunction with the broad field covered 
by the various Divisions of the Institute, is a guarantee of 
efficient service along these special lines. 

This Division has been engaged on a number of prob- 
lems of a highly important nature, some of w^hich have 
been successfully solved, while others promise to develop 
interesting results. It is believed that the coordination of 
theory with practice, that is made possible by this Division, 
will be appreciated by producers and manufacturers who 
wish to broaden or reduce the costs of their production by 
availing themselves of the latest and best scientific methods. 

26 



REPORTS AND PUBLICATIONS 

THE Institute issues from time to time printed bulle- 
tins, circulars and reports containing the results of 
investigation or covering some special field of infor- 
mation. In addition to the printed matter, typewritten 
reports are furnished to clients on special investigations. 
Following the practice of the best laboratories, such re- 
ports are ordinarily submitted with the understanding that 
they are not to be used for advertising purposes except in 
cases in which special arrangement to this end has been 
made and in which due regard to dignity and ethical prin- 
ciples has been taken into consideration.
